I know it's bad form to reply to your own messages but I had some
email from Wayne Self which reminded me that I didn't tell you exactly
what I am dealing with.
I have a P2/200/64mb/2gb running a recent version of STABLE
(3.2 I think) with only video and ethernet cards and both serial ports
turned on in the BIOS. The kernel recognizes both PORTS (sio0 & sio1)
when it boots but I still have the situation described here. Also
possibly of note is the fact that I am still running kernel.GENERIC on
this box as I haven't had time to recompile it yet. Surely running the
generic kernel wouldn't cause it to not talk to a serial device?
/snips for clarity/
Ok I dug out the cu man page and followed your directions which was
the same as my original plan to talk to each port but now I have run
up on something stranger. Whenever I cu -l/dev/cuaa0 [-s115200 or
-s1200] (this meaning with no speed option or with either 115200 or
1200 speed option) I get "Connected." but that's all I ever receive
from the port. I issue several AT commands (ATZ ATE0 AT ATZ ATE1 AT
ATZ ~.) ((all followed by a <CR> of course)) and I get nothing. Next I
do the same thing with cuaa1 and I never get "Connected." so I am
assuming my modem is on cuaa0 since it connects but I cannot
successfully send commands to it. The modem is a USR 28.8 Sportster
and if I recall my AT commands ATE1 enables local echo from the modem,
but even there I have myself covered by having an ATE0 as well.
